Principally the packing Finally, the paper is out off along the dashstep consists in piling the disks into tubes, deand-dot line d. The flap e obtained in this man- 55 ner is secured around the cartridge, for example by means of gummed paper strips or the like J. After that the cartridge is closed at one end and the tube is drawn off at the other end over a mandrel g, which may be solid or tubular. During this operation the disks are kept in position within the cartridge by means of the mandrel. After the tube has been drawn off also the other end of the cartridge is closed, after which the packing operation is finished. The cartridge has now the appearance shown in Figure 3 The packing may also be carried out mechanically in the following manner:

The tube a is held against a fixed support placed between two cylinders r, s. The tube is drawn over a mandrel as for instance in Figure 2, and the disks as are deposited in the groove between the two cylinders as shown in Figure 3a. The disks 001 are kept in such a position that they remain at a right angle to the axis of the cylinders T, s, where they can be easily inspected. The wrapping paper I) is inserted between the disks, and the cylinder 1". An upper cylinder t is moved against the disks. By revolving the two cylinders r, s in the direction of the arrows the wrapping paper is fed around the disks assisted by guides it. After the wrapping paper has been cut to suitable length a suitable number of gummed paper strips is inserted between the wrapping paper now rolled around the disks, and one of the revolving cylinders.

The gummed paper strip follows the wrapping paper and closes the side of the cartridge containing the disks. The cylinder t is removed from the cartridge for instance to the position shown by dash-and-dot lines in Figure 3a, and the end of the wrapping paper is folded in a suitable manner to prevent the disks from falling out of the cartridge.

When introducing the cartridge into the magazine tube k, which in Figure 4 is shown to be connected to a feeding tube m, the workman should pay attention to the flap e or edge h, which must extend outside the slit Z in the wall of the tube, after the cartridge has reached its final position in the tube. He then grasps the flap (as is shown in Figure 4), or the edge h. of the paper (as is shown in Figure 4a), and draws out the paper. The disks are now ready to sink through the tube m down to a conveyor (not shown) and gradually one disk after the other is fed by the conveyor to the place, where they are inserted .into the cap shells. In Fig. 4d the reference character 1) indicates a fixed paper knife for opening the cartridge.

In the tube battery exemplified in Figure 5 about twenty magazine tubes is are mounted to a unit. All of them are secured to a holder 2 consisting of two horizontal plates in holes drilled along the periphery of the upper plate. The holder is secured to a vertical shaft, which is revolvable in a bearing 3, provided on the underside of the underlying stationary plate 4, which forms the bottom of the tubes It and by means of brackets is secured to the upper side of the machine 5. The said stationary plate is provided with one hole, to which the feeding pipe m is connected.

In the shown. embodiment the battery is mounted on a capping machine with a cork feeding mechanism 6 of a known type, which has been put out of function. This arrangement shows that the invention may be-used also in machines already being in use in plants or the like, as well as in such machines of special constructions and also in machines of different constructions. For revolving the battery, so that each tube will come above the tube m in its proper turn, for example, the following provision may be made:

Into each battery tube a, loose weight or some other part moving with the disks is put on the pile of cork disks, the said weight, when the tube has been discharged, cutting in an electric con tact In, by which an electromagnet is put into function. locking pin 1, which holds the battery in correct position, and then a draw bar 8 of a blocking device on the battery shaft, so that the said bar is moved aside and is then grasped by a peg on the vertical shaft 9, which is in permanent rotation, by which the battery is revolved one step, so that the next filled tube will come right above the feeding pipe m, the locking pin returning to locking position. Alternatively, the driving device for the battery may be driven mechanically throughout and in driving connection with some shaft in the machine. The tubes is are detachable, so that they may be filled while the machine 5 is in operation and from either end.

Of course, the above described packing method may be used for plates of varying shape and size in various piles butsubstantially of equal shape and size in one and the same pile.

Having now described my invention, what I claim .as new'and desire to secure by Letters Patent is:

1. The method of packing sealing disks for bottle cap shells, which method consists in placing a tube containing juxtaposed disks upon a continuously rotating support thereby imparting a rolling movement to said tube and disks, removing the tube to expose the rolling disks, introducing a wrapper about the rolling disks between the latter and the rotating support and removably pressing the wrapper against the rolling disks beyond the support to produce a tightly wound cartridge for introduction into a tubular magazine.

2. A method of packing sealing disks for bottle cap shells, as claimed in claim 1, in which the disks, being different on one side than on the other, are turned while being exposed to place corresponding sides in the same direction.
